Update: Thought I broke my mint 12-2

Okay, so I finally sat down to clean the gun and measure endshake. Cleaning took almost no time at all since I only put about 50 rounds through it and the previous owner may have shot twice that. No crud under the star, hardly any on the forcing cone, etc. So then I took out my feeler gauges and found the "problem", such as it is. Just holding the gun in my hand the cylinder gap is .0015, and pulling back on the cylinder I can get a .002 blade in there but .0025 stops at the right side of the forcing cone. This is one tight mamma-jamma! Now that I know that, I've had time to reflect on the issue and I'm just going to use a rag to wipe off the forcing cone when it gets sticky and resume firing after that. If the gun is set up this tight I'd rather not risk messing it up by removing too much material.

Thanks to all the folks that offered their assistance on my first thread.

Glad you got it cleared up. I bought one a year or so ago, and it quickly became my everyday carry gun. Good shooting gun.

That is too tight a barrel-cylinder gap. If you fire even one cylinder full rapidly, there is a good chance of the gun hanging up and become unusable until it cools. It has nothing to do with crud or dirt, but with longitudinal expansion of the cylinder due to heat, something no amount of cleaning can stop. If it were my gun, and I wanted it for anything but a slow fire range toy, I would take that b-c gap up to .006-007".
